Is water corrosive to copper?
Copper doesn’t corrode.” It won’t corrode under most common circumstances (metal and oxygen in the presence of water) like steel and iron will. But exposure to certain chemicals and compounds sometimes found in water—especially water coming from a well—will create specific types of corrosion in copper.
What causes copper pipes to erode?
So what is “hard water” and why does it corrode your copper pipes? Hard water is water with a high concentration of dissolved minerals like calcium, magnesium and other metals. Over time, these metals can wear out the inner lining of copper pipes, eventually creating pinhole leaks.
Is Rusty copper dangerous?
What health problems can corrosion cause? Copper and lead can be toxic and can leach into tap water in older or in new homes. This leaching is caused by corrosion. Copper contamination can cause gastrointestinal problems in the short term and damage the liver and kidneys over time.
What can be done about corroded copper pipes?
This results in blue-colored water. Water supply companies are aware of corrosion problems within specific areas. Scientists have studied the effect of various chemicals in reducing corrosion in copper pipes. One of the most effective is the addition of orthophosphate to water in water plants.
What causes water to leak from copper pipes?
The problems manifest themselves in either leaks or high copper levels and blue water. Copper pipes can leak due to various forms of pitting attack or erosion corrosion while copper alloys, especially brass fittings, can undergo dezincification or stress corrosion cracking.
How does Copper get into your drinking water?
However, where copper pipes corrode they can release copper into your drinking water to a level that can affect its quality and safety. The information contained in this guide will help you identify signs of copper corrosion and provide advice on how to minimise its effect on your health. How does copper get into drinking water?
What can I do about iron in my water pipes?
More common in private wells than public supplies, iron and iron derivatives in water pipes can be removed using several different methods. Test the water to determine iron as well as other mineral levels. Your local municipality may offer testing. Water testing kits are also available online.

What happens if you have iron in Your Water?
This can cause your pipes to clog up, leading to clogged toilets and sinks and a reduced water pressure in your house. Bacteria that is attached to the iron causes brown slime to build up in your pipes and wherever you have water in your house. A sudden release of the residue in your pipes can lead to a sudden rush of discolored water.
What causes corrosion in lead and copper pipes?
corrosion product layers, possibly containing copper phosphate, which can easily spall off the bore of the pipes. The phosphate derives from the dosing of phosphate into water supplies by water companies in order to reduce corrosion of old lead pipes.
Can a copper hot water system cause corrosion?
On the other hand, problems with copper corrosion are rarely encountered in normal residential houses. For instance, erosion corrosion which may occur in large buildings with recirculating hot water systems virtually never happens in normal residential houses even if the water is fully softened.
